Open File in a Servlet-Method

Hi @ all,
I want to open a simple textfile in my Servlet-Java Method
on a Resin Aplication Server. But I don't know how I have
to build my path. I actually don't know on which plattform
the Resin is running (not I set up the Resin), but I think its a Windows- or Unix-PC.
How should I build the path? ("../test.txt" or "c:\resin\tmp\test.txt")
Thanks and bye
Ben

Forward slashes works fine on Windows. Backslash does not work on unix. And "c:" does not exist on unix. So of the two you mention, "../test.txt" is far more portable.
Other options are to require the filename (or directory) in the startup parameters for the servlet, or to use ClassLoader.getResource().

Opening files with servlet

Okay... I'm new to using servlets. Not so much to jsp, just to using servlets. I have one process on our site that is using servlets and I'm trying to mimic how that is using em but am having no luck.
I am trying to open files with a servlet. I have the class built and compiled, but mainly pulled it from Java World. I evenually will need to pass the servlet the filename and path I want open but in this example it has the file set. My problem is I want to send users to a jsp file where I check user authentication and call the servlet to open the doc, but I don't know how to call the servelet or what to send it. If someone could maybe walk me through this.
Here's my servlet:
package cmxx.fileServe;
import java.io.*;
import java.util.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class fileServe extends HttpServlet {
final static String CONTENT_TYPE_DOC = "application/msword";
final static String CONTENT_TYPE_HTML = "text/html";
final static String document = "/docs/form_41.doc";
public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException
doGet(request, response);
public void doGet (HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException
PrintWriter out;
out = response.getWriter();
HttpSession websession = request.getSession(true);
response.reset();
response.setDateHeader ("Expires", 0);
response.setDateHeader("max-age", 0);
try {
     response.setContentType(CONTENT_TYPE_DOC);
FileInputStream fileInputStream = new FileInputStream(document);
ServletOutputStream servletOutputStream = response.getOutputStream();
int bytesRead = 0;
byte byteArray[] = new byte[4096];
while((bytesRead = fileInputStream.read(byteArray)) != -1) {
     servletOutputStream.write(byteArray, 0, bytesRead);
servletOutputStream.flush();
servletOutputStream.close();
fileInputStream.close();
} catch(Exception ex) {
     throw new ServletException(ex.getMessage());
} /* end doget */
} /* end class */

I'm trying a new servlet. But am getting a few compile errors. Can someone help?

"Preview this File" Does Nothing + Blinding GTK+ open file dialogs...

...I have two problems in KDEMod4...did anyone have these problems and how do you fix them?
Right clicking a file and clicking "Preview this File" does nothing...including folder views, Konqueror, and Dolphin.
GTK+ open file dialogs alternate between the normal background for my text box and blindingly white background.

Hi,
I also have the same problem, but with my JNI and C++ expertise, I was able to isolate the problem.
My platform:
- Microsoft Windows XP, Family Edition (French), Version 2002, Service Pack 3
- JRE 1.6.0_21
In the source of the JDK6 (Src/windows/classes/sun/awt/windows/WDesktopPeer.java), the Desktop.open(file) calls the native method
ShellExecute(*uri.toString()*, "open")
For example, if you try to open "c:\helloworld.pdf",
uri.toString() = "*file:/c:/helloworld.pdf*"if I call ShellExecute("C:\\helloworld.pdf", "open"), it works
but if I call ShellExecute(" file:/c:/helloworld.pdf", "open"), it doesn't work on my platform.
In both case, the ShellExecuteW or ShellExecuteA function of the Windows API return the integer 42 (> 32), saying that the functions succeeded. If the file object is not correct, the function should return a value <= 32.
=> The bug is not due to Java implementation, but to a bug in the Windows API.
Other remark:
I also tried the "ShellExec_RunDLL" entry point of the Shell32.dll library using RunDll32 utility. Both commands below are running correctly:
rundll32 SHELL32.DLL,ShellExec_RunDLL "C:\hello.pdf"
rundll32 SHELL32.DLL,ShellExec_RunDLL "file:/C:/hello.pdf"My conclusion:
1) A workaround could be implemented in the JRE: use the file path without the "file:/" protocol prefix.
2) This bug seems to be present only one some version of Windows XP (to confirm).

Desktop.getInstance().open(file) does nothing (nothing happens)

I 've seen this on a user's computer:
Desktop.getInstance().open(myFile);
does nothing: no exception, no stacktrace, nothing.
It doesn't work for pdf or for xls files (and probably for all other file types too).
However, if he double clicks on a pdf or xls file in Windows Explorer it opens (in acrobat reader / MS Excel).
This also works in DOS-prompt: "start C:\myFile.pdf"
Making it canonical first doesn't work either:
Desktop.getInstance().open(myFile.getCanonicalFile());
Environment:
Java 6 update 16
Windows XP SP 3
A webstart application with all security permissions.
I've removed all JRE's and even removed the USER_HOME/application data/Sun map.
He upgraded from Windows XP SP2 to SP3 with no change.
Has anyone any idea what is causing this?

PROBLEM while using URL in order to open a file from a servlet

Hi,
I am having a problem while trying to open a file from my servlet by using URL connection. Following is my code sample. what happens is when I first run my project it opens the file but after that when I rerun it again and again it sometimes opens it and sometimes not. if it can't open it it gives an error saying "the file is damaged and couldn't be repaired". I don't get any exceptions. if you guys can help me I will appreciate it so much... thanks.
here is my code :
URL url = new URL("http://demobcs.ibm.com:81/test.pdf");
resp.setContentType(getContentType("http://demobcs.ibm.com:81/test.pdf"));
          ServletOutputStream sos = null;
          BufferedInputStream bis = null;
          try {
               sos = resp.getOutputStream();
          } catch (Exception e) {
               System.out.println("exception !!!!");
               e.printStackTrace();
          System.out.println("burada2");
          try {
               byte[] bytes = new byte[4096];
               //bis = new BufferedInputStream(conn.getInputStream());
               DataInputStream in = new DataInputStream(url.openStream());
               //DataInputStream in = new DataInputStream(conn.getInputStream());
               bis = new BufferedInputStream(in);
               int j;
               while ((j = bis.read(bytes, 0, 4096)) != -1) {
                    try {
                         sos.write(bytes, 0, 4096);
                         System.out.println("file is being read ...:");
                    } catch (Exception e) {
                         e.printStackTrace();
               in.close();
               bis.close();
               //sos.close();

               System.out.println("exception :"+e.toString());
               e.printStackTrace();

You are writing (<filesize> mod 4096) bytes of crap at the end of the file. Use your variable j instead for the number of bytes to write in your loop.

Open File Dialog appears TWICE when using servlet to download an attachment

Hi,
This is KILLING me!!! Please HELP.....
I am using a servlet to download an xml file, which I build on the fly based on user interaction.
The open file dialog appears nicely and I hit open. The dialog pops up again immediately and I have to click open again in order to open the file.
This works fine when file extension is txt and I DONOT have to click twice. Here is the code:
String xmlString = getXMLString(); //builds xml
String fileName = "myFile.xml";
response.setContentType("application/x-download");
response.setHeader("Content-disposition", "attachment;filename=" +fileName);
PrintWriter out = response.getWriter();
out.print(xmlString);
out.flush();
I am using IE6.0 sp2

When install QuickTime7.7.1 and QT SDK's interface(OpenMovieFile method) open file failed

Hi guys.
I use QT SDK to write a sample to load movie files.
when install QuickTime7.7.1 and call QT SDK's interface(OpenMovieFile method) to open file, it doesn't work. i will get error(-36). but when i use QT 7.6.9, it works well.
so how can i use QT SDK(install QT7.7.1 and OS is windows xp) to open movie file which fullpath include wide unicode characters(like D:\Media動画).
much appreciate.

Tif files not opening via Acrobat Javascript openDoc() method

Hi,
I am trying to open a .tif file via Acrobat Javascript using the following code snippet which I have in config.js file in Acrobat Javascripts folder:
trustedOpenDoc = app.trustedFunction( function (File)
app.beginPriv();
var doc = app.openDoc({
cPath: File,
bUseConv: true
app.endPriv();
return doc;
Problem is that openDoc opens up all other images but it has problem with multi page tif files, I mean it does not open some tif files. I have directly tried to open files in Acrobat professional 8/9 from File --> Open but got same result.
The same happens also with some heavy (above 1 MB) .bmp files but with .bmp files this behaviour is not so frequent, on the other hand .tif files always give the same result.
Any PDF Gladiator who can save my project deadline!
Look please; I have this problem for the last 12 days and miserably my project is getting late becoz of this.
Thanks in advance for the resolution/suggestion.

You guys are not getting my point.
I am using Adobe Acrobat Professional 8/9 for creating a PDF that picks up text files and image (Jpg, bmp, tif) files from a network shared folder and inserts them into an empty Template PDF file by making use of Acrobat events through Javascript.
This all works fine as long I dont include any Tif file and PDF is created successfully.
Now all other file types including text files, jpgs, gif are opening up but problem is with .tif files.
You can check this by directly opening image files in Adobe Acrobat Profesional 8/9 from File --> Open menu option.
Other images will open up but most Tif files won't open in it. Such tif files also not open in "Winodws Picture and Fax Viewer" software but will open in softwares like "Imaging Professional" , "IrfanView" etc, which I think use some special codec for it.
If you know of any Acrobat plugin that can be incorporated in Acrobat professional and convert these tif files to PDF on the fly, would be of great help or have some any other suggestion you feel is right.
Thanks

Thanks & Regards,

Sorry for the late resp. Here's what dev suggests be investigated:
I would want to know:
Can they do a "$ORACLE_HOME/bin/dmstool -dump" and
save/compress/send the results?
Are there any errors printed in the Apache error_log while this leak occurs?
The customer could/should re-check their TCP settings, especially the TCP time wait interval and generally follow the TCP settings recommended in Chapter 5 of the iAS Performance Guide for 9.0.2.
Is there anything else interesting/unusual about the site?
Let us know how it goes.

Sudden increase in open file descriptors

Our system is live since an year and half and for the first time I encountered the following exception
"java.net.SocketException: Too many open files"
When our internet application stopped responding I immediately checked the number of open file descriptors on my Solaris machine by using the "lsof" command and found that it was an abnormal 600 value and as I continued monitoring it reached 1024 in matter of minutes and WebLogic gave the above exception. The current setting for file descriptors is 1024. But all these days the average number of open file descriptors was well below 220.
I also took thread dumps and found that most of the threads were stuck at the following location
""ExecuteThread: '3' for queue: 'weblogic.kernel.Default'" daemon prio=5 tid=0x00883a90 nid=0x10 runnable [6d080000..6d0819c0]

There is no file descriptor leak in the application. My question is since all the threads are hung at JDBC and socket level, does it mean that a faulty query would have triggered this problem(may be the database was too busy executing a faulty query).
I suspect this because I recieved a database exception soon after the problem appeared. One of my database insert transaction had timed out after 300 seconds. Also this was the first time I recieved this kind of an exception
java.sql.SQLException: The transaction is no longer active - status: 'Marked rollback. [Reason=weblogic.transaction.internal.TimedOutException: Transaction timed out after 299 seconds

Any inputs regarding this problem?

Hi,
I am using WebLogic 8.1 SP2 on a Solaris machine.Ok, good enough. Once WebLogic times out a transaction, it rolls it back on the
connection. That Sybase driver's rollback doesn't unfortunately affect it's
own running statements. For 81sp3 we added code to explicitly cancel any ongoing
statement during a rollback. This may be what you need to free up those
threads and the socekts the driver may be keeping open. If you can upgrade
to a newer version of 8.1, this code will free you up. Alternately, you can
try either upgrading to Sybase'e latest driver or to our BEA driver for Sybase.
Ask support for the latest BEA driver package for 8.1.

Problem:Accessing the file system with servlets ???

Hi...
I have a strange problem with my servlets that run on Win2000 with Apache and 2 Tomcat instances.
I cannot open files through servlets whereas exactly the same code lines work in local standalone java programm.
It seems to be somehting like a rights problem...but I dont know what to do.
thanks for any help

Hi joshman,
no I didn't get error messages as the relevant lines for reading/writing where between try statements, but you were where right it was/is just a simple path problem.
I expected the refering directory without using a path to be the directory where the servlet is in, but it is not !!??
Do you know if I set this in the setclasspath.bat of tomcat ?

Finder throwing error -1401 when attempting to open files on mounted volume

Alright, this is driving me nuts. At random, Finder will refuse to open files on a mounted volume on my server. It throws the error "The application can't be opened. -1401" and then "The operation can’t be completed. An unexpected error occurred (error code -1401)." back to back. It doesn't matter what the file type is, as far as I can tell (.jpg, .xlsx and .pdf are on there).
From that point on, I can navigate those volumes to the point that I have navigated them since the volume was mounted at start up, but can't go any deeper into the directories or open anything. Finder also won't eject the volume. I can't open files from within applications, either.
I have to reboot for it to work again.
However, if I jump into Parallels I can open anything on the server. Even Acrobat files, which open in the Mac environment and not within the virtual machine.
Does anyone have any insight to what might be causing this? I searched and can't find anything.
Thanks,
Brian

Restart your computer with the Shift key held down,
and then open the Startup Items folder inside the
System Folder. Throw away all of the aliases you find
in this folder and then empty the trash.
To quit AppleWorks or another application when it
won't respond, hold down the Option, Command, and Esc
keys, and then click the Force Quit button. You
should also use the Disk First Aid application in the
Applications (Mac OS 9):Utilities folder to verify
your hard disk, as something may have been damaged
when you shut the machine down using that method.

Snow Leopard 10.6.2 CS4 InDesign can't open files with a "#" in file path

Snow Leopard 10.6.2 CS4 InDesign can't open files with a "#" in file path using any of these perfectly normal methods:
1. double-click file in the Finder (e.g in a Folder on your Mac or on your Mac desktop etc.)
2. select file and choose "File... Open" command-o in the Finder
3. drag file to the application icon in the Finder.
4. Select file in Bridge and double-click, choose File.. Open.. or Drag icon to InDesign icon in dock.
If you try to open an ID file named with a "#", you will get an error message "Missing required parameter 'from' for event 'open.'"
This happens to any InDesign file that has a "#" (pound sign, number sign, or hash) in the filename or in the file path (any parent folder).
To reproduce
Name an InDesign file Test#.idd Try to open it in the Finder or Bridge (as opposed to the "Open" dilaog of InDeisng itself).
"Solution"
The file WILL open using File... Open... command-o while in InDesign application.
Rename the file or folders that have a "#" (shift-3) in the filename.
Report to Adobe if it bugs you.
This does not occur in "plain" Leopard 10.5 nor Tiger 10.4
Untested in Panther or before and
Untested with CS3 and earlier in Snow Leaopard.
Anyone have those and want to try this... ?

In case this really bothers you: we've added a workaround for this into Soxy. If you enable the option, these documents will open fine on double-click.
You need Soxy 1.0.7 from:
http://www.rorohiko.com/soxy
Go to the 'Soxy' - 'Preferences' - 'Other' dialog window, and enable 'Open InDesign via Script'
(Irrelevant background info (it's all invisible to the user): the workaround works by special-casing how Soxy opens documents in InDesign: instead of using AppleScript, Soxy will use ExtendScript to instruct InDesign to open the document - which works fine).
